APPARATUS FOR PRODUCING ILLUSORY EFFECTS.

Specification of Letters Patent.

Patented Sept. 19, 1911.

Application filed October 15, 1910. Serial No. 587,190.

To all whom it may concern:

' Be it known that; I, Roy M. HLLL, a citizen ot the Unittd States, and resident of Soinerville, in the county 01. Middlesex and State of illassaehusetts, have invented certain new and useful llIlPIUVClIlQIllS in Apparatus tor Producing illusory El'l'ects, of which the following is a specification.

My in.'ention relates to amusement apatratus and particularly to amusement apparatus for producing an illusory etli'ect and its organization comprises a. vessel, a sup ply pipe for the vessel, an exhaust pipe for the vessel, and means [or cirtatlating a liquid through said pipes and vessel, one of said pipes extending into the discharge end of the other so that the inner pipe is hidden by the discharge from the other pipe.

Referring to the accompanying t'lrawing, \\llltll shows my invention, the apparatus is divided by the partition into two sections 1) and (I, the section l3 being the part visible to the observer and the section (J being hidden l'ron'i view by the partition to render the illusion more ell'ective. A pump l of ordinary construction mounted on any suitable foundation has its inlet connected with an exhaust pipe or tube 2 and its outlet; with a supply pipe or tube-2i. A vessel l which is preferably of transparent inaterial may be supported in any suitable manner as by a plurality of chains?) hanging from a support above. The chains ii support the vessel i so that the inlet end ol exhaust pipe 2 is well within the vessel, prc'lerably near the bottom ol the latter. The supply pipe 3 incloses the exhaust pipe 2 for a part of its length near the vessel l, but its discharge end is arranged some distaneo'above the vessel t so that the contents of supply pipe 3 .lalls from the discharge end of the latter into vessel tin a cylindrical. column, as indicated at .1', surrounding amlbiding from view the inlet end ol pipe 2 which projects downwa dly 'l'rom pipe 2-5.. 'lhat part ol supply pipe 3 which surrounds exhaust pipe 2 is sullieiently large in diameter to maintain the capacity of said pipe the same throughout. its length, the capacities ol the two pipes '3 and 3 being alike. ."l'lupump 1 maintains the same rate ol.

'llow ol: the liquid through the pipes 2 and 3 undsiuee these pipes are of the same capacity it follows that there will be no substantial variance in the volume of the contents of the vessel st at any time while the apparatus is in operation.

In the preferred form of my invention the appamtus, or that part of it which is unhidden by the partition A, is of glass or other transparent material, but my invention not limited in this respect and said parts may be of any suitable material. In most cases the best results will be secured ill an opaque or non-transparentliquid is employed which will hide the protruding inlet. end of the exhaust pipe Pump 1 may be driven in any suitable manner as by a belt 6 engaging a pulley 7.

From the above description it will be seen thatmy improved amusement; apparatus may be used to advantage to display oils and other liquids as well as l'o an'utsement purposes, and also for advertising pt'trposes.

.l urthernuire, the apparatus is ot very simple and inexpensive construction.

What I claim is:

1.. An apparatus of the character described comprising a vessel; a supply pipe discharging into said vessel having its dis charge end arranged above and some distance away from said vessel; an exhaust pipe for said vessel extending upward into the discharge end of the supply pipe so that it is hidden by the discharge from the latter, and means for circulating a liquid through said pipes and vessel.

An apparatus oi. the character described comprising a vessel; a supply pipe discharging into said vessel; an exhaust pipe for said vessel having its inlet end arranged within the latter. said exhaust pipe being arranged within the supply pipe and projecting from the latter into the vessel so that it is hidden by the discharge from the supply pipe, and means to circulate a liquid through said pipes and vessel.

3. .\n apparatus ol. the character described comprising a vessel; a supply pipe discharging into said vessel and having its discharge end arranged above and some distance away l'rom said vessel; an exhaust pipe for said vessel, said exhaust pipe lead ing upward l'rom a point within said vesst-l into and through the supply pipe so that its protruding end is -l i lden, by the discharge from the supply pipe, and means for circulating a liquid through said pipes pipes and vessel, the inlet of said pump be and vessel. I ing connected With the exhaust pipe and 4. An apparatus of the character dethe outlet of said pump being connected scribed comprising a vessel; a supply pipe With the supply pipe; i
